OWASSO, Okla. - While responding to a house fire Tuesday night Owasso firefighters stumbled on a marijuana grow operation.

Firefighters were called to a home near East 101st Street North and North 142nd East Avenue around 10 p.m., and while extinguishing the fire, crews found a hidden room in the attic with what police call "a large marijuana cultivation system" and a number of marijuana plants.

Police were called to the scene and the homeowner admitted to the grow operation, giving consent to search the home, said Deputy Chief of Police Jason Woodruff.
